<div class="section"><h2 class="sectiontitle">Description</h2>
<p>The class <span class="keyword">graph_node</span> is a base class for all flow graph nodes.  The virtual destructor allows flow graph nodes to be destroyed through pointers to <span class="keyword">graph_node</span>.  For example, a <span class="keyword">vector&lt; graph_node * &gt;</span> could be used to hold the addresses of flow graph nodes that will later need to be destroyed.</p>
